Association of TAP1 and TAP2 gene polymorphisms with hematological malignancies.
Transporter associated with antigen presenting (TAP) 1 and TAP2 genes are localized in the major histocompatability complex (MHC) class II region and form a heterodimer playing a key role in endogenous pathways for antigen presentation. Defects of these genes have been reported to be common in different types of cancer. Polymorphisms identified in these loci have also been investigated and repo...
متن کاملDownregulation of TAP1 and TAP2 in early stage breast cancer
TAP1-TAP2 heterodimeric complexes are recognized as the transporter associated with antigen processing of major histocompatibility complex class I peptides for recognition by tumor-specific cytotoxic T lymphocytes. In this study, we investigated the immunohistochemical expression of TAP1 and TAP2 in 160 patients with breast cancer and correlated their expression levels with clinicopathologic pa...
متن کاملCatalytic site modifications of TAP1 and TAP2 and their functional consequences.
The transporter associated with antigen processing (TAP), a member of the ATP binding cassette (ABC) family of transmembrane transporters, transports peptides across the endoplasmic reticulum membrane for assembly of major histocompatibility complex class I molecules. Two subunits, TAP1 and TAP2, are required for peptide transport, and ATP hydrolysis by TAP1.TAP2 complexes is important for tran...
متن کاملAssociation of TAP1 and TAP2 Gene Polymorphisms with Susceptibility to Pulmonary Tuberculosis.
TAP1 and TAP2 genes encode heterodimeric molecule involved in endogenous antigen processing. The present study was undertaken to find out the possible association between TAP1 and TAP2 polymorphisms and risk of pulmonary tuberculosis (PTB) in a sample of Iranian population. Polymorphisms of TAP1 (rs1057141, rs1135216) and TAP2 (rs2228396, rs241447, rs67511411, rs141555015) were determined in 17...
متن کاملHead–head/tail–tail relative orientation of the pore-forming domains of the heterodimeric ABC transporter TAP
BACKGROUND The transporter associated with antigen processing (TAP) is a heterodimeric member of the large family of ABC transporters. The study of interactions between the subunits TAP1 and TAP2 can reveal the relative orientation of the transmembrane segments, which form a translocation pore for peptides. This is essential for understanding the architecture of TAP and other ABC transporters. ...
